Font Validator: Add ability to collect fonts

[FichteFoll]

Instead of verifying whether a muxed script (or a list of fonts) is complete, it would be better to automate the collection of fonts to mux in the first place.

I imagine this as a different subcommand next to the current verify. Name suggestions for the tool include "assfont" and "fontcheck".

As for the operation, of the list or collect command, I would like to either receive a list of fonts on stdout I can parse or have the matched fonts copied into a specified target folder. Font matching could be performed using system fonts (which would probably require using fontconfig directly or some form of emulation on Linux and idk about Windows) or from a list of specified paths like ~/.fonts, which should already be possible for the verify task.
